You can't pirate AI services. You either get a local image generator, or pay for a service.
If you want to get unlimited prompts you can pay 25 dollars for their opus tier. But that's about it.
The reason you can't is because AI services cannot be "pirated" as you would pirate a normal program. Basically, what companies like NovelAI sell you is not an inherent produt, it's the ability to tell THEIR program what to do, program of which, runs on their machines exclusively, and is therefore literally impossible to pirate.
That's how any AI service works. It's running on the servers of the company you're paying, not your computer.
If you wanna run a similar image generator for free on your computer though, it is possible. There are various open source alternatives, but you're gonna have to set it up yourself, and you'll require a good amount of VRAM in your graphics card in order to generate good images (8 or more)
There are various detailed guides on how to do it on the internet, but given the fact that you didn't know that it is not possible to pirate AI services, I'm presuming you don't have the tech savyness and/or computer hardware required to set up such a thing, so happy research/saving. Or pay for a service that does it for you, like CivitAI or NovelAI itself.
P.S: CivitAI, which is a website, has free generations you get each day, that you can even make NSFW with, so if you really want it and for some reason are super poor and your computer is shit, I'd say go for that.
